I lApplication;-fled December 20, 1923, Serial No. 681,709. RenewedNovember 4, 1926.

This invention relates to a method for assembling the blanks of a fibershipping case of -a specilied construction. In my Patent i in . oncertain conveyor systems. However, the

No. 1,375,127, dated April 19, 1921, and in the Lemon Patent No.1,428,597 ldated Septemper 12th, 1922, a shipping case is shown in whichthree blanks are employed, namely,

a body blank folded to provide the bottom, i two side walls and thecover wings, and providedl at the-ends ofthe two side walls and.thebottom with end flaps. The other two blanks comprise each an endwall provided e with, a sealing flap. These sealing fiaps are arrangedto be engaged with the cover wings for sealing the case.

A container of this character has great possibilities in its commercialappeal for the reason that it involves a large saving in material, andthe bottom and side walls are kept free of all flaps which areobjectionable in sliding the box-or 1n carrying the box great practicalobjection to a box of. this kind at the present time is the cost ofassembling the box, as each end has to be separately inserted andstitchedseparately on a wire stitching head. 'lhis involvesconjsiderable labor cost land quite large capital investment to dprovidethe stitching ma# chines necessary to stitch these containers together.lt is the object ol the present in-l vention to provide a new and novelmethod ot' handling and stitching these blanks to'- V "ether whereby thefasteners or .stilchesmay be driven iu simultaneously in two rows,thereby substantially cutting the labor cost in two, and considerablylessicniug the capital investment in a large plant where a shipperrequires a/number of machines for assembling thc boxes.I I

'In the drawinvs:

Eig. 7 a perspective, showing the` third above referred to. However, inm`y prior patent, flaps are provided on the cover wings', but this isimmaterial so far as` the Vmethod ot' assembling the blanks that formLemon, and also shown in my prior patent the container is concerned."The bodyblank 'is scored and cut. to fdrm two cover win s a and b, twoside walls c and d, and one e ottom all e. The end flaps l', 9,751', jwud/c are provided on the two endsof the two i side walls and thebottomwall. ,The two end blanks are designated m and 1i and each isprovided with a sealing'tlap, one designated o and the other p. Theusual way of assembling a boxl of this kind is to fold together the bodyblank to form a bottom andtwo side walls, insert an end blank andi` thenseparately stitch down the three end flaps over the endvblank; then thecase is reversed and the opposite end blank is put in inexactly thelsame way. lhis requires alto,- gether too much time foizassembly. It isalsotoo large a labor cost. i

I very materially,lessenthe cost of assembly by my new'` method. In thefirst I step,'the two end blanks m and n arev secured to the bottomwallvof'the body blank on opposite sides byfsimultaneously stitching theflaps g' and j to. these yend walls as shown in Fig. 4 where thestitches are taken in the order designated l, 2, 3, 4, 5. and 6.

" Now conceivably, these stitches or fasteners could be driven in onopposite sides by 'any operator driving the `fasteners in with a hundtool,'one operator being/ stationed on `each side. y commerciallypractical way of handling the blanks, and to do this workin thequickestk However, this would not be a possible time, a` pair of a'nvilsr and sare rovided, which are s aced substantially the ength of thecase. ver these anvils will be supprted a pair of stitchin heads such asshown in my prior Patent o. 1,430,150.

The next step is to fold thebox up as shown in Fig. 6fand to present thesame to the two anvils whichl are spaced apart sub-l stantially the'.width of the case.` The stitches vbe driven in by a machine.

7, 8, 9, 10, and 1l and 12 are then taken simultaneously on oppositesides. These fasteners could conceivably be driven by two operators onopposite sides of the avils, but obviously for practical purposes theywould The case is then reversed and the stitches 13, 14, 15, 16, 17 and18 taken on the same pair of anvils stitching on opposite sides of thecase, being done simultaneously either by two workmen equipped with handtools or by two stitching heads. y

In factories engaged in large production the end blanks would be rststitched to the ends of the bottom walls on one machine. The stitchedblanks then would be carried to a second machine where the second andthird steps would be taken. However, it is possible to perform the threestitches on a single machine by first stitching all the blanks togetherso that the end blanks adhere to the ends of the bottom wall, thenchanging the adjustable spacing of the anvils and stitching heads so asto accommodate them to the width of the case; be giventhe second andthird stitches to complete the assembly.

lllhat l.' claim is:

l. The method of assembling a shipping case constructed of 'three blankscomprising two end blanks and single body blank the latter including twoside walls with an intervening bottoni wall and all three walls havingmid ai; their ends, which comprises the simultaneously securing the twoend blanks te the flaps at the ends of the bottom wall, second. foldingthe body blank to bring the side walls in parallelism and simultaneouslysecuring the end flaps of two of the side walls to one end blank. thenthird, simultaneously securing the remaining two end flaps of the twoside walls io the other end blank.-

2. The method of assembling a .shipping case constructed of three blankscomprising two end blanks and a single body blank the latter includingtwo side walls with an intervening bottom wall and all three wallshaving end flaps at their ends, which comliirises` simultaneouslysecuring the two end blanks to the end flaps of the bottom wall, thenfolding the body blank to bring the two side walls in parallelism andsecuring the end llapsof the two side walls to one end blank and thensecuring the remaining two side tiaps of the two side walls to the otherend blank to complete the assembly'.

3. The method of assembling a shipping case constructed of three blankscomprising two end blanks and a single body blank the latter includingtwo side walls with an intervening bottom walt and all three wallshaving end flaps at their ends, which cointhen the blanks may all blanksto the opposite ends of the bottom' wall, the folding of the body blankto bring 'the side walls in parallelism, and folding over the end 'flapson the two side walls against an end blank, and over a pair of anvilsspaced apart to tit within the width of the case, then simultaneouslydriving two rows of metallic fasteners through the two flaps into theend blank to secure the same together, and third, reversing the case andplacingit over the anvils and securing the remaining end flaps to theother end blank by driving simultaneously two rows of metallic fastenersthrough the flaps and into the cnd blank. y

4. The method'of assembling a shipping case constructed of three blankscomprising two end blanks and a single body blank-the latter includingtwo side -walls with yan intervening bottom wall and all three walls yhaving end flaps at theirends, which comprises the laying of the bodyblank and two end blanks on two anvils spaced substanl tially the lengthof the case with the end flaps of the bottom wall in engagement with theend blanks and simultaneously stitching the two opposite end flaps ofthe bottoni wall to the end blanks, and then stitching the remainingflaps to the end blanks to4 complete the assembly. Y

The method of assembling a shipping case constructed of three blankscomprising two end blanks and a single body blank the latter includingtwo side walls willi an inter-A vening bottoni wall and all lthree wallshaving end flaps at their ends, which comprises the laying of the bodyblank on two anvils spaced substantially the length of thc case, theplacing of the end blanks in contact with the end fiaps of the bottom ofthe body blank. the simultaneous stitching of such end flaps to the endblanks, secondly, the removal of the blanks and the folding of the sametov bring the side walls into parallclisi'n,

'and the end flaps at one end of the two side walls into contact withone of the end blanks over the two anvils spaced to fit within the-width of the case, then simultaneously stitching such two flaps to theend blank, then reversing the case and bringing the remaining two endflaps in contact with the remaining end blank and simultaneouslystitching the same to the end blank.'
